Abstract: The invention concerns a method for a multi-port node (110) having a
shared buffer memory (240) to provide enhanced data packet buffering capacity for
established virtual circuits (VC's) through the node and one of its output ports (220)
while maintaining grades of service commitments. The method admits incoming
data packets to a node for an established VC based on a determination of
combination of factors including the effective memory requirements for each output
port as VC's are created or terminated, the portions of buffer memory in use for
conveying packets through the intended output port for the incoming packet, and the
total amount of available shared memory in the node. Such determinations enable
the node to better decide whether admitting the incoming packet would cause a
disproportionate allocation of the shared memory for the intended output port. As a
consequence, a relatively high packet buffering capacity can be achieved
substantially without violating grades of service commitments.

IPC: G02F1/015
Filed: 1998-03-31
Abstract: An apparatus includes a driving voltage generator that
generates a pulse driving voltage having a rising edge
and a decaying edge. An optical modulator produces
a first pulse at the rising edge of the pulse driving
voltage and a second pulse at the decaying edge of the
pulse driving voltage. Therefore, the first and
second pulses are both produced from a single driving
pulse voltage. The frequency of the first pulse is
determined by the slope of the rising edge of the
pulse driving voltage and the frequency of the second
pulse is determined by the slope of the decaying edge
of the pulse driving voltage. The first and second
pulses are transmitted through a transmission line.
A detection device detects the first and second pulses
after being transmitted through the transmission line.
A processor then determines the amount of dispersion
in the transmission line by comparing the time
interval between the detected first and second pulses
to the time interval of the first and second pulses 
before being transmitted. Generally, the optical
modulator is a Mach-Zehnder modulator driven with a
pulse driving voltage exceeding the half-wavelength
voltage of the modulator.

Abstract: It is arranged such that the least common multiple of two
numbers m and n of which one is prime to the other, is made as
large as possible where the number m is the rotational speed
(rpm) of a platen with a polishing pad affixed thereto and the
number n is the rotational speed (rpm) of a carrier with a
wafer mounted thereon. As a result of such arrangement, it is
not until the platen completes m revolutions that a point on
the polishing pad that comes into contact with a fixed point
on the wafer returns to the original contact point with the
fixed point at the start of polishing, and the resulting
trajectory is therefore spread uniformly over the polishing
pad. Each point on the wafer is brought into contact with most
surface regions of the polishing pad, therefore preventing the
wafer from undergoing deterioration in planarity uniformity due
to a particular point on the wafer, on one hand, frequently
coming into contact with low polishing-rate regions in the
polishing pad and due to the other points on the wafer, on the
other hand, less frequently coming into contact with the
regions.

der Messung berechnet. Während der Fahrt werden in einer
Nachverarbeitung neben den obengenannten Informationen über
Feldstärke an der Omni-Antenne (2) und an der Rotorantenne
(1), die Fahrzeugausrichtung und die geographische Position
des Fahrzeugs erfaßt, zum Beispiel mittels des Global

Auswertung von Differenzsignalen, soweit die erforderliche
Meßgenauigkeit dies verlangt. In einer Nachverarbeitungsoperation
werden dann lagerichtig die jeweiligen Werte der
Feldstärke durch die geographischen Koordinaten

Abstract: The dynamic gain control system includes a pump source providing pump light.
The dynamic gain control system measures a certain portion of the input pump light
into the optical amplifier and measures a certain portion of the output pump light from
the optical amplifier. The dynamic gain control determines the pump light loss based
on the input pump light and output pump light measurements. Based on the pump
light loss, the dynamic gain control system maintains the pump light loss relatively
constant (for example 0. 1dB) independent of the number of input channels and their
relative powers (for example, input channel powers of -50 dBm to 10 dBm) by
providing feedback to control the output pump light. In doing so, the dynamic gain
control system maintains the inversion level of the optical amplifier. A relatively
constant inversion level corresponds to only small variations in the gains of the input
channels (multi-channel gain) as a result of changes in the input channels to the optical
amplifier.

Abstract: A method of minimizing power consumption within an
electronic price label (EPL) (18) which conserves life of
its battery (40). A time period for removing power from a
transceiver (44) within the EPL is determined by a computer
(12) from price change frequency data. A message to control
circuitry within the EPL is sent by the computer as soon as
possible following a change in price displayed by the EPL.
The message includes a command to remove power from the
transceiver and the power down time period. Power is
removed from the transceiver by the control circuitry. The
control circuitry counts until the power down time period is
exhausted. Power is applied to the transceiver by the
control circuitry when the power down time period is
exhausted. Finally, a first time within the control
circuitry is synchronized by the control circuitry to a
second time indicated by the computer after the power down
timer period is exhausted and before any additional message
is sent to the EPL.
